如果我们现在不采取行动，我们的孩子继承的世界将比我们得到的更加贫瘠。
If we don’t do something now, the world our children inherit will be much poorer than the one we were given.
相信自己和你所拥有的一切。知道你内心有一种力量，比任何障碍都更强大。
The preservation of the means of knowledge among the lowest ranks is of more importance to the public than all the property of all the rich men in the country.
